HOLLYWOOD, Calif. — Music star Kelis has filed for divorced from rapper Nas, despite being seven months pregnant with the couple's son.

"I can confirm that she has filed for divorce," a rep for the "Milkshake" singer told Vibe. "We request the media to respect her privacy during this very difficult time."

An attorney for Kelis filed the divorce papers Thursday afternoon, citing irreconcilable differences, according to the publication.

Kelis, 29, and Nas, 35, met in 2002 at an MTV Video Music Awards after-party thrown by Sean "Diddy" Combs. They tied the knot three years later in Atlanta.

While this is the couple's first child together, Nas has a 15-year-old daughter named Destiny from a previous relationship. After learning he had a second child on the way, the "Hip Hop Is Dead" singer expressed his enthusiasm to MTV.

"Yeah, man, I find out what it's gonna be next week, so I'm happy," he said.
